[Eccrine adenocarcinoma in a patient with familial breast carcinoma].
A 67-year-old patient developed a subcutaneous, non-tender nodule in her left groin over a period of about seven years. The patient underwent surgery and 4 procedures were required to obtain complete excision. The histopathologic findings showed eccrine adenocarcinoma, a member of the heterogeneous group of sweat gland tumors which occur primarily in adults with a peak of 50-60 years of age. Sweat gland carcinomas are extremely rare neoplasms of the skin and exhibit a slow growth rate with a rather high local recurrence rate. The tumor has a disposition to metastasize and shows a poor response rate to adjuvant therapy regimens. Therefore wide, deep surgical excision with an excision margin of 2-3 cm is the treatment of choice. Nevertheless there are some case reports on successful therapy of a metastasized sweat gland carcinoma with 5-fluorouracil and tamoxifen. Here further studies are needed to achieve a better survival rate for patients with metastatic disease.
